RELATED APPLICATIONS

This application is a continuation of U.S. Ser. No. 15/750,809, filed Feb. 6, 2018 which is a national phase application of PCT Application No. PCT/US2016/045804, filed Aug. 5, 2016; which claims the benefit of provisional application U.S. Ser. No. 62/202,552, filed Aug. 7, 2015, the contents of each of which are herein incorporated by reference in their entirety.

FIELD OF THE DISCLOSURE

The disclosure is directed to fields of small molecules, medicine, inflammation, and allergy. Specifically, the disclosure is directed to the use of a mast cell stabilizer or a composition comprising a mast cell stabilizer for the treatment of a mast cell related disorder by systemic administration of the mast cell stabilizer.

BACKGROUND

Mast cells play a key role in the inflammatory process. They are found in the perivascular spaces of most tissues and contain pro-inflammatory and vasoactive mediators, such as serine proteases, tryptase, histamine, serotonin, proteoglycans, thromboxane, prostaglandin D2, leukotriene C4, platelet-activating factor, and eosinophil chemotactic factor. When activated, mast cells rapidly release granules and various hormone mediators into the interstitium, a process referred to as degranulation. Degranulation of mast cells can be caused by physical or chemical injury, crosslinking of immunoglobulin G receptors, or by activated complement proteins.

Systemic mast cell related disorders may result from excessive proliferation of mast cells or abnormal release of pro-inflammatory and vasoactive mediators. Symptoms of systemic mast cell related disorders include pruritus, flushing, nausea, vomiting, diarrhea, headaches, abdominal pain, vascular instability, urticaria, itching, and anaphylaxis. Accumulation of mast cells in the skin, gastrointestinal tract, bone marrow, liver, spleen, and lymph nodes may result in a particular systemic mast cell related disorder, systemic mastocytosis, or mastocytosis.

The utility of mast cell stabilizers in the treatment of systemic mast cell related disorders, such as mastocytosis, has been limited. For example, cromolyn sodium (also known as disodium cromoglycate or DSCG) was first approved in 1973 and is widely considered safe, but it has found limited utility because the amount of the compound that can be delivered systemically is inadequate. An oral solution of cromolyn sodium is available for the treatment of systemic mast cell related disorders, such as mastocytosis (Gastrocrom®). However, the oral solution is only modestly effective for treating localized gastrointestinal symptoms, and it is not effective for the treatment of systemic symptoms because of the low oral bioavailability of cromolyn sodium (less than 1%).

Efforts have been made to increase the oral bioavailability of cromolyn sodium in order to provide systemically effective amounts for the treatment of systemic mast cell related disorders, but these efforts have not yielded products that achieve significantly higher oral bioavailability of cromolyn sodium in a practical, safe, and well-tolerated manner. Accordingly, a need exists for methods of delivering mast cell stabilizers, such as cromolyn sodium, that achieve higher systemic levels than previously considered or thought possible, in a practical, safe, and well-tolerated manner, in order to significantly improve clinical outcomes for patients suffering from systemic mast cell related disorders.

DETAILED DESCRIPTION

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of skill in the art to which the inventions described herein belong. All publications, patents, and patent applications mentioned in this specification are hereby incorporated by reference to the same extent as if each individual publication, patent, or patent application was specifically and individually indicated to be incorporated by reference.

Definition of Terms

As used herein, the term “about” is used synonymously with the term “approximately.” Illustratively, the use of the term “about” with regard to a certain therapeutically effective pharmaceutical dose indicates that values in a range spanning a cited value, e.g., plus or minus up to 10% of a cited value, are also effective and safe.

As used herein, the terms “comprising,” “including,” “such as,” and “for example” (or “e.g.”) are used in their open, non-limiting sense.

As used herein, the phrase “consisting essentially of” is a transitional phrase used in a claim to indicate that the following list of ingredients, parts or process steps must be present in the claimed composition, machine or process, but that the claim is open to unlisted ingredients, parts or process steps that do not materially affect the basic and novel properties of the invention.

“Nominal dose,” as used herein, refers to the loaded dose, which is the amount of mast cell stabilizer in an inhalation device prior to administration to the patient. The volume of solution containing the nominal dose is referred to as the “fill volume.”

“AUC_(last)” as used herein refers to the area under the curve from time zero to time of last measurable concentration of active pharmaceutical ingredient (API).

“AUC_(last) ^(HEN)” as used herein refers to the area under a blood plasma concentration curve up to the last time point for the nominal dose of active pharmaceutical ingredient (API) administered with a high efficiency nebulizer.

“AUC_(last) ^(Conv)” as used herein refers to the area under a blood plasma concentration curve up to the last time point for a nominal dose of active pharmaceutical ingredient (API) administered with a conventional inhalation device.

“AUC_((0-∞))” as used herein refers to the total area under a blood plasma concentration curve for an active pharmaceutical ingredient (API).

“AUC_((0-∞)) ^(HEN)” as used herein refers to the total area under a blood plasma concentration curve for a nominal dose of active pharmaceutical ingredient (API) administered with a high efficiency nebulizer.

“AUC_((0-∞)) ^(CONV)” as used herein refers to the total area under a blood plasma concentration curve for a nominal dose of active pharmaceutical ingredient (API) administered with a conventional inhalation device.

AUC_((0-∞)) can be determined by methods known to those of skill in the art. For example, the AUC(0-∞) of an API can be determined by collecting blood samples from a subject at various time points after administration of an API to the subject, separating plasma from the blood samples, extracting the API from the separated plasma samples, e.g., by solid-phase extraction, quantifying the amount of the API extracted from each sample of separated plasma, e.g., by liquid chromatography-tandem mass spectrometry (LC-MS/MS), plotting the concentration of API in each sample versus the time of collection after administration, and calculating the area under the curve.

“Substantially the same nominal dose” as used herein means that a first nominal dose of an active pharmaceutical ingredient (API) contains approximately the same number of millimoles of the mast cell stabilizer as a second nominal dose of the mast cell stabilizer.

“Bioavailability” as used herein refers to the amount of unchanged API that reaches the systemic circulation, expressed as a percentage of the dosage of the API that is administered to a subject. By definition, the bioavailability of an intravenous solution containing the active pharmaceutical ingredient (API) is 100%. The bioavailability of an API can be determined by methods known to those of skill in the art. For example, the bioavailability of an API can be determined by collecting urine samples from a subject at various time points following administration of the API to the subject, extracting the API from the urine samples, e.g., by solid-phase extraction, quantifying the amount of the API in each urine sample, adjusting the amount of API collected from the urine by a factor based on the amount of API reaching systemic circulation that is excreted in the urine, and calculating the percentage of the API administered to the subject that reaches the systemic circulation of the subject. In a specific embodiment, the bioavailability of cromolyn sodium can be determined as described in Walker et al., 24 J. Pharm. Pharmacol. 525-31 (1972). In the case of cromolyn sodium, the amount of the compound isolated from the urine is multiplied by two to calculate the total amount reaching systemic circulation after administration because the compound is known to be excreted unmetabolized in equal parts in the urine and feces, i.e., approximately 50% of the amount of cromolyn sodium that reaches systemic circulation is excreted in the urine and approximately 50% of the amount of cromolyn sodium that reaches systemic circulation is excreted in the feces.

“Enhanced lung deposition” as used herein refers to an increase in drug deposition (deposited lung dose) arising out of, for example, improved efficiency of drug delivery.

“Deposited dose” or “deposited lung dose” is the amount of mast cell stabilizer deposited in the lung. The deposited dose or deposited lung dose may be expressed in absolute terms, for example in mg or μg of API deposited in the lungs. The deposited lung dose may also be expressed in relative terms, for example calculating the amount of API deposited as a percentage of the nominal dose.

“C_(max)” as used herein refers to the maximum plasma concentration for an active pharmaceutical ingredient (API).

“C_(max) ^(HEN)” as used herein refers to the maximum blood plasma concentration for a nominal dose of the active pharmaceutical ingredient (API) administered with a high efficiency nebulizer.

“C_(max) ^(CONV)” as used herein refers to the maximum blood plasma concentration for a nominal dose of the active pharmaceutical ingredient (API) administered with a conventional inhalation device.

C_(max) can be determined by methods known to those of skill in the art. For example, the C_(max) of an API can be determined by collecting blood samples from a subject at various time points after administration of an API to the subject, separating plasma from the blood samples, extracting the API from the separated plasma samples, e.g., by solid-phase extraction, quantifying the amount of the API extracted from each sample of separated plasma, e.g., by LC-MS/MS, plotting the concentration of API in each sample versus the time of collection after administration, and identifying the peak concentration of the API on the curve.

“Enhanced pharmacokinetic profile” means an improvement in some pharmacokinetic parameter. Pharmacokinetic parameters that may be improved include AUC (0-4 or 0-6 or 0-8 h), AUC_(last), AUC_((0-∞)), T_(max), T_(1/2), and C_(max). In some embodiments, the enhanced pharmacokinetic profile may be measured quantitatively by comparing a pharmacokinetic parameter obtained for a nominal dose of an active pharmaceutical ingredient (API) administered by one route of administration, such as an inhalation device (e.g., a high efficiency nebulizer) with the same pharmacokinetic parameter obtained with the same nominal dose of active pharmaceutical ingredient (API) administered by a different route of administration, such as a different type of inhalation device or an oral formulation (e.g., oral tablet, oral capsule, or oral solution).

“Blood plasma concentration” refers to the concentration of an active pharmaceutical ingredient (API) in the plasma component of blood of a subject or patient population.

“Patient” or “subject” refers to the animal (especially mammal) or human being treated.

A “subject group” or “patient group” has a sufficient number of subjects or patients to provide a statistically significant average measurement of the relevant pharmacokinetic parameter. All members of the “subject group” or “patient group” have pharmacokinetic parameters for the mast cell stabilizers that fall within statistically normal ranges (i.e., there are no outliers), and no member is included on the basis of non-standard or unusual measurements.

“Nebulizer,” as used herein, refers to a device that turns medications, compositions, formulations, suspensions, and mixtures, etc. into a fine aerosol mist for delivery to the lungs.

“Drug absorption” or simply “absorption” typically refers to the process of movement of drug from site of delivery of a drug across a barrier into a blood vessel or the site of action, e.g., a drug being absorbed via the pulmonary capillary beds of the alveoli into the systemic circulation.

“T_(max)” as used herein refers to the amount of time necessary for an active pharmaceutical ingredient (API) to attain maximum blood plasma concentration.

“T_(max) ^(HEN)” as used herein refers to the amount of time necessary for a nominal dose of an active pharmaceutical ingredient (API) to attain maximum blood plasma concentration after administration with a high efficiency nebulizer.

“T_(max) ^(CONV)” as used herein refers to the amount of time necessary for a nominal dose of an active pharmaceutical ingredient (API) to attain maximum blood plasma concentration after administration with a conventional inhalation device.

The term “treat” and its grammatical variants (e.g., “to treat,” “treating,” and “treatment”) refer to administration of an active pharmaceutical ingredient to a patient with the purpose of ameliorating or reducing the incidence of one or more symptoms of a condition or disease state in the patient. Such symptoms may be chronic or acute; and such amelioration may be partial or complete. In the present context, treatment entails administering a mast cell stabilizer to a patient via any route of administration disclosed herein.

As used herein, the term “high concentration” refers to a concentration greater than 1% by weight. For example, in a specific embodiment, a “high concentration” formulation of cromolyn sodium comprises cromolyn sodium at a concentration of greater than 1% by weight.

As used herein, the term “hypotonic” refers to a formulation that has a tonicity less than 295 mOsm/kg.

The term “prophylaxis” refers to administration of an active pharmaceutical ingredient to a patient with the purpose of reducing the occurrence or recurrence of one or more acute symptoms associated with a disease state or a condition in the patient. In the present context, prophylaxis entails administering a mast cell stabilizer to a patient via any route of administration disclosed herein. Thus, prophylaxis includes reduction in the occurrence or recurrence rate of a systemic mast cell related disorder. However, prophylaxis is not intended to include complete prevention of onset of a disease state or a condition in a patient who has not previously been identified as suffering from the disease or the condition.

As used herein, a “systemically effective amount” is an amount of mast cell stabilizer in the body of a patient as a whole that is effective for the treatment or prophylaxis of a systemic mast cell related disorder. A “systemically effective amount” may be expressed, for example, as the mass of a mast cell stabilizer, or concentration of a mast cell stabilizer, in a patient's plasma. A “systemically effective amount” may differ depending on the specific mast cell stabilizer and the specific systemic mast cell related disorder.

As used herein, a “locally effective amount” is an amount of mast cell stabilizer in a particular region of the body of a patient that is effective for the treatment or prophylaxis of a systemic mast cell related disorder disclosed herein. A “locally effective amount” may be expressed, for example, as the mass of a mast cell stabilizer, or concentration of a mast cell stabilizer, in a patient's tissue. A “locally effective amount” may differ depending on the specific mast cell stabilizer and the specific mast cell related disorder.

As used herein, a difference is “significant” if a person skilled in the art would recognize that the difference is probably real. In some embodiments, significance may be determined statistically, in which case two measured parameters may be referred to as statistically significant. In some embodiments, statistical significance may be quantified in terms of a stated confidence interval (CI), e.g., greater than 90%, greater than 95%, greater than 98%, etc. In some embodiments, statistical significance may be quantified in terms of a p value, e.g., less than 0.5, less than 0.1, less than 0.05, etc. The person skilled in the art will recognize these expressions of significance and will know how to apply them appropriately to the specific parameters that are being compared.

WO2010/042504; WO85/02541; WO2014/115098; WO2005/063732; WO2009/131695; and WO2010/088455; the contents of which are each incorporated herein by reference. Mast cell stabilizers, including cromolyn and pharmaceutically acceptable salts, prodrugs, and adducts thereof, may be prepared by methods known in the art.

In some embodiments, mast cell stabilizers described herein may be prepared as prodrugs. A “prodrug” refers to an agent that is converted into the parent drug in vivo. The prodrug can be designed to alter the metabolic stability or the transport characteristics of a drug, to mask side effects or toxicity, to improve the flavor of a drug, or to alter other characteristics or properties of a drug. In some embodiments, the prodrug has improved bioavailability relative to the parent drug. In some embodiments, the prodrug has improved solubility in pharmaceutical compositions over the parent drug. In some embodiments, prodrugs may be designed as reversible drug derivatives, for use as modifiers to enhance drug transport to site-specific tissues. In some embodiments, a prodrug of a mast cell stabilizer is an ester of the mast cell stabilizer, which is hydrolyzed to the carboxylic acid, the parent mast cell stabilizer. In some embodiments, a prodrug comprises a short peptide (polyamino acid) bonded to an acid group, wherein the peptide is metabolized in vivo to reveal the parent drug. In certain embodiments, upon in vivo administration, a prodrug is chemically converted to the biologically, pharmaceutically or therapeutically active form of the mast cell stabilizer. In certain embodiments, a prodrug is enzymatically metabolized by one or more steps or processes to the parent mast cell stabilizer. In certain embodiments, the mast cell stabilizer is a prodrug of cromolyn. In a specific embodiment, the prodrug of cromolyn is cromoglicate lisetil.

To produce a prodrug, a pharmaceutically active mast cell stabilizer compound is modified such that the active compound will be regenerated upon in vivo administration. In some embodiments, prodrugs of mast cell stabilizers are designed by virtue of knowledge of pharmacodynamic processes and drug metabolism in vivo. See, e.g., Nogrady (1985) Medicinal Chemistry A Biochemical Approach, Oxford University Press, New York, pages 388-392; Silverman (1992), The Organic Chemistry of Drug Design and Drug Action, Academic Press, Inc., San Diego, pages 352-401, Saulnier et al., (1994), Bioorganic and Medicinal Chemistry Letters, Vol. 4, p. 1985; Rooseboom et al., Pharmacological Reviews, 56:53-102, 2004; Miller et al., J. Med. Chem. Vol. 46, no. 24, 5097-5116, 2003; Aesop Cho, “Recent Advances in Oral Prodrug Discovery”, Annual Reports in Medicinal Chemistry, Vol. 41, 395-407, 2006.

In some embodiments, mast cell stabilizers described herein include isotopically-labeled compounds, which are identical to those recited herein, but for the fact that one or more atoms are replaced by an atom having an atomic mass or mass number different from the atomic mass or mass number usually found in nature. Examples of isotopes that can be incorporated into the present compounds include isotopes of hydrogen, carbon, nitrogen, oxygen, fluorine and chlorine, such as, for example, ²H, ³H, ¹³C, ¹⁴C, ¹⁵N, ¹⁸O, ¹⁷O, ³⁵S, ¹⁸F, ³⁶Cl, respectively. Certain isotopically labeled compounds described herein, for example those with isotopes such as deuterium, i.e., ²H, can afford certain therapeutic advantages resulting from greater metabolic stability, such as, for example, increased in vivo half-life or reduced dosage requirements. In certain embodiments, the mast cell stabilizer is isotopically labeled cromolyn, or a pharmaceutically acceptable salt thereof, such as cromolyn sodium. In some embodiments, the mast cell stabilizer is deuterium-labeled cromolyn sodium.

In some embodiments, mast cell stabilizers described herein may be PEGylated, wherein one or more polyethylene glycol (PEG) polymers are covalently attached to the mast cell stabilizers. In some embodiments, pegylated mast cell stabilizers increase the half-life of the mast cell stabilizers in the body. In some embodiments, pegylation of the mast cell stabilizers increases the hydrodynamic size of the mast cell stabilizers and reduces their renal clearance. In some embodiments, pegylation of the mast cell stabilizers increases the solubility of the mast cell stabilizers. In some embodiments, pegylation of the mast cell stabilizers protects the mast cell stabilizers from proteolytic degradation.

Albumin proteins found in the plasma bind some pharmaceutical compounds to form complexes. Complexation of albumin with pharmaceutical compounds, e.g., mast cell stabilizers, can influence the pharmaceutical compounds' plasma half-life and/or biological half-life in the body by preventing metabolism and/or excretion of the complexed compounds. In some embodiments, compositions disclosed herein include albumin and a mast cell stabilizer, e.g., cromolyn sodium.

“Antifoaming agents” reduce foaming during processing which can result in coagulation of aqueous dispersions, bubbles in the finished film, or generally impair processing. Exemplary anti-foaming agents include silicon emulsions or sorbitan sesquoleate.

Solid Oral Formulations

In some embodiments, the solid dosage forms disclosed herein may be in the form of a tablet, (including a suspension tablet, a fast-melt tablet, a bite-disintegration tablet, a rapid-disintegration tablet, an effervescent tablet, an osmotic pump tablet, or a caplet), a pill, a powder (including a sterile packaged powder, a dispensable powder, or an effervescent powder), a capsule (including both soft or hard capsules, e.g., capsules made from animal-derived gelatin or plant-derived HPMC, or “sprinkle capsules”), solid dispersion, solid solution, bioerodible dosage form, controlled release formulations, pulsatile release dosage forms, multiparticulate dosage forms, pellets, or granules. In some embodiments, systemically effective amounts of mast cell stabilizers are achieved with solid oral formulations by including one or more of permeation enhancers and enteric coatings in the solid oral formulations. In some embodiments, enteric coatings regulate the delivery a mast cell stabilizer during its passage through the stomach and intestine.

The pharmaceutical solid dosage forms described herein can include a mast cell stabilizer and one or more pharmaceutically inactive ingredients such as a compatible carrier, binder, filling agent, suspending agent, flavoring agent, sweetening agent, disintegrating agent, dispersing agent, surfactant, lubricant, colorant, diluent, solubilizer, moistening agent, plasticizer, stabilizer, penetration enhancer, wetting agent, anti-foaming agent, antioxidant, preservative, or one or more combination thereof.

In some embodiments, solid dosage forms, e.g., tablets, effervescent tablets, and capsules, are prepared by mixing particles of a mast cell stabilizer with one or more pharmaceutical excipients to form a bulk blend composition. When referring to these bulk blend compositions as homogeneous, it is meant that the particles of the mast cell stabilizer are dispersed evenly throughout the composition so that the composition may be readily subdivided into equally effective unit dosage forms, such as tablets, pills, and capsules. The individual unit dosages may also include film coatings, which disintegrate upon oral ingestion or upon contact with diluent. These formulations can be manufactured by conventional pharmacological techniques, e.g., one or a combination of: (1) dry mixing, (2) direct compression, (3) milling, (4) dry or non-aqueous granulation, (5) wet granulation, and (6) fusion. See, e.g., Lachman et al., The Theory and Practice of Industrial Pharmacy (1986). Other methods include, e.g., spray drying, pan coating, melt granulation, granulation, fluidized bed spray drying or coating (e.g., wurster coating), tangential coating, top spraying, tableting, extruding and the like.

Pharmaceutical preparations for oral use can be obtained by mixing one or more solid excipient with one or more mast cell stabilizers, optionally grinding the resulting mixture, and processing the mixture of granules, after adding suitable auxiliaries, if desired, to obtain tablets or dragee cores. In some embodiments, dragee cores are provided with suitable coatings. For this purpose, concentrated sugar solutions may be used, which may optionally contain gum arabic, talc, polyvinylpyrrolidone, carbopol gel, polyethylene glycol, and/or titanium dioxide, lacquer solutions, and suitable organic solvents or solvent mixtures. Dyestuffs or pigments may be added to the tablets or dragee coatings for identification or to characterize different combinations of active compound doses.

In other embodiments, a powder including a mast cell stabilizer may be formulated to include one or more pharmaceutical excipients and flavors. Such a powder may be prepared, for example, by mixing the formulation and optional pharmaceutical excipients to form a bulk blend composition. Additional embodiments also include a suspending agent and/or a wetting agent. This bulk blend is uniformly subdivided into unit dosage packaging or multi-dosage packaging units.

Compressed tablets are solid dosage forms prepared by compacting the bulk blend of the formulations described above. In some embodiments, the compressed tablets will include a film surrounding the final compressed tablet. In some embodiments, the film coating can provide a delayed release of the mast cell stabilizer from the formulation. In other embodiments, the film coating aids in patient compliance. Film coatings such as Opadry® typically range from about 1% to about 3% of the tablet weight. In other embodiments, the compressed tablets include one or more pharmaceutical excipients.

A capsule may be prepared, for example, by placing the bulk blend of the formulation of the mast cell stabilizer inside of a capsule. In some embodiments, the formulations (non-aqueous suspensions and solutions) are placed in a soft gelatin capsule. In other embodiments, the formulations are placed in standard gelatin capsules or non-gelatin capsules such as capsules comprising HPMC. In other embodiments, the formulation is placed in a sprinkle capsule, wherein the capsule may be swallowed whole or the capsule may be opened and the contents sprinkled on food prior to eating. In some embodiments, the therapeutic dose is split into multiple (e.g., two, three, or four) capsules. In some embodiments, the entire dose of the formulation is delivered in a capsule form.

In some embodiments, dosage forms may include microencapsulated formulations. Materials useful for the microencapsulation include materials compatible with mast cell stabilizers, which sufficiently isolate mast cell stabilizers from other non-compatible excipients. Materials compatible with mast cell stabilizers are those that delay the release of the mast cell stabilizers in vivo. Exemplary microencapsulation materials useful for delaying the release of the formulations include, but are not limited to, hydroxypropyl cellulose ethers (HPC) such as Klucel® or Nisso HPC, low-substituted hydroxypropyl cellulose ethers (L-HPC), hydroxypropyl methyl cellulose ethers (HPMC) such as Seppifilm-LC, Pharmacoat®, Metolose SR, Methocel®-E, Opadry YS, PrimaFlo, Benecel MP824, and Benecel MP843, methylcellulose polymers such as Methocel®-A, hydroxypropylmethylcellulose acetate stearate Aqoat (HF-LS, HF-LG, HF-MS) and Metolose®, Ethylcelluloses (EC) and mixtures thereof such as E461, Ethocel®, Aqualon®-EC, Surelease®, Polyvinyl alcohol (PVA) such as Opadry AMB, hydroxyethylcelluloses such as Natrosol®, carboxymethylcelluloses and salts of carboxymethylcelluloses (CMC) such as Aqualon®-CMC, polyvinyl alcohol and polyethylene glycol co-polymers such as Kollicoat IR®, monoglycerides (Myverol), triglycerides (KLX), polyethylene glycols, modified food starch, acrylic polymers and mixtures of acrylic polymers with cellulose ethers such as Eudragit® EPO, Eudragit® L30D-55, Eudragit® FS 30D Eudragit® L100-55, Eudragit® L100, Eudragit® 5100, Eudragit® RD100, Eudragit® E100, Eudragit® L12.5, Eudragit® 512.5, Eudragit® NE30D, and Eudragit® NE 40D, cellulose acetate phthalate, sepifilms such as mixtures of HPMC and stearic acid, cyclodextrins, and mixtures of these materials. In some embodiments, plasticizers such as polyethylene glycols, e.g., PEG 300, PEG 400, PEG 600, PEG 1450, PEG 3350, and PEG 800, stearic acid, propylene glycol, oleic acid, and triacetin are incorporated into the microencapsulation material.

Microencapsulated mast cell stabilizers may be formulated by methods known by one of ordinary skill in the art. Such known methods include, e.g., spray drying processes, spinning disk-solvent processes, hot melt processes, spray chilling methods, fluidized bed, electrostatic deposition, centrifugal extrusion, rotational suspension separation, polymerization at liquid-gas or solid-gas interface, pressure extrusion, or spraying solvent extraction bath. In addition to these, several chemical techniques, e.g., complex coacervation, solvent evaporation, polymer-polymer incompatibility, interfacial polymerization in liquid media, in situ polymerization, in-liquid drying, and desolvation in liquid media could also be used. Furthermore, other methods such as roller compaction, extrusion/spheronization, coacervation, or nanoparticle coating may also be used.

In other embodiments, the formulations described herein are solid dispersions. Methods of producing such solid dispersions are known in the art and include, but are not limited to, for example, U.S. Pat. Nos. 4,343,789, 5,340,591, 5,456,923, 5,700,485, and 5,723,269, as well as U.S. Pub. Appl. 2004/0013734, each of which is specifically incorporated by reference herein. In still other embodiments, the formulations described herein are solid solutions. Solid solutions incorporate a substance together with the mast cell stabilizer and other excipients such that heating the mixture results in dissolution of the drug and the resulting composition is then cooled to provide a solid blend which can be further formulated or directly added to a capsule or compressed into a tablet. Methods of producing such solid solutions are known in the art and include, but are not limited to, for example, U.S. Pat. Nos. 4,151,273, 5,281,420, and 6,083,518, each of which is specifically incorporated by reference herein.

In other embodiments, formulations described herein include a matrix based dosage form. In a matrix-based dosage form described herein, at least one mast cell stabilizer and optional pharmaceutically acceptable excipient(s) are dispersed within a polymeric matrix, which typically comprises one or more water-soluble polymers and/or one or more water-insoluble polymers. The drug can be released from the dosage form by diffusion and/or erosion. Suitable water-soluble polymers include, but are not limited to, polyvinyl alcohol, polyvinylpyrrolidone, methylcellulose, hydroxypropylcellulose, hydroxypropylmethylcellulose, or polyethylene glycol, and/or mixtures thereof. Suitable water-insoluble polymers also include, but are not limited to, ethylcellulose, cellulose acetate, cellulose propionate, cellulose acetate propionate, cellulose acetate butyrate, cellulose acetate phthalate, cellulose triacetate, poly (methyl methacrylate), poly (ethyl methacrylate), poly (butyl methacrylate), poly (isobutyl methacrylate), and poly (hexyl methacrylate), poly (isodecyl methacrylate), poly (lauryl methacrylate), poly (phenylmethacrylate), poly (methyl acrylate), poly (isopropyl acrylate), poly (isobutyl acrylate), poly (octadecyl acrylate), poly (ethylene), poly (ethylene) low density, poly (ethylene) high density, poly (ethylene oxide), poly (ethylene terephthalate), poly (vinyl isobutyl ether), poly (vinyl acetate), poly (vinyl chloride) or polyurethane, an d/or mixtures thereof. Suitable pharmaceutically acceptable excipients include, but are not limited to, carriers, such as sodium citrate and dicalcium phosphate; fillers or extenders, such as stearates, silicas, gypsum, starches, lactose, sucrose, glucose, mannitol, talc, and silicic acid; binders, such as hydroxypropyl methylcellulose, hydroxymethyl-cellulose, alginates, gelatin, polyvinyl pyrrolidone, sucrose, and acacia; humectants, such as glycerol; disintegrating agents, such as agar, calcium carbonate, potato and tapioca starch, alginic acid, certain silicates, EXPLOTAB, crospovidone, and sodium carbonate; solution retarding agents, such as paraffin; absorption accelerators, such as quaternary ammonium compounds; wetting agents, such as cetyl alcohol and glycerol monostearate; absorbents, such as kaolin and bentonite clay; lubricants, such as talc, calcium stearate, magnesium stearate, solid polyethylene glycols, and sodium lauryl sulfate; stabilizers, such as fumaric acid; coloring agents; buffering agents; dispersing agents; preservatives; organic acids; and organic bases. The aforementioned excipients are given as examples only and are not meant to include all possible choices. Additionally, many excipients can have more than one role or function, or can be classified in more than one group; the classifications are descriptive only, and are not intended to limit any use of a particular excipient.

Matrix formulations of the present invention can be prepared by using, for example, direct compression or wet granulation. A functional coating can then be applied. Additionally, a barrier or sealant coat can be applied over a matrix tablet core prior to application of a functional coating. The barrier or sealant coat can serve the purpose of separating an active ingredient from a functional coating, which can interact with the active ingredient, or it can prevent moisture from contacting the active ingredient.

In some embodiments, the modified-release formulations described herein are provided as osmotic pump dosage forms. In an osmotic pump dosage form, a core containing at least one mast cell stabilizer and optionally at least one osmotic excipient is typically encased by a selectively permeable membrane having at least one orifice. The selectively permeable membrane is generally permeable to water, but impermeable to the drug. When the system is exposed to body fluids, water penetrates through the selectively permeable membrane into the core containing the drug and optional osmotic excipients. The osmotic pressure increases within the dosage form. Consequently, the drug is released through the orifice(s) in an attempt to equalize the osmotic pressure across the selectively permeable membrane.

In more complex pumps, the dosage form can contain two internal compartments in the core. The first compartment contains the drug and the second compartment can contain a polymer, which swells on contact with aqueous fluid. After ingestion, this polymer swells into the drug-containing compartment, diminishing the volume occupied by the drug, thereby forcing the drug from the device at a controlled rate over an extended period of time. Such dosage forms are often used when a zero order release profile is desired. Suitable swellable polymers typically interact with water and/or aqueous biological fluids, which causes them to swell or expand to an equilibrium state. Acceptable polymers exhibit the ability to swell in water and/or aqueous biological fluids, retaining a significant portion of such imbibed fluids within their polymeric structure, so as to increase the hydrostatic pressure within the dosage form. The polymers can swell or expand to a very high degree, usually exhibiting a 2- to 50-fold volume increase. The polymers can be non-cross-linked or cross-linked. In some embodiments, the swellable polymers are hydrophilic polymers.

In some embodiments, mast cell stabilizers can be provided in a multiparticulate membrane-modified formulation. Membrane-modified formulations can be made by preparing a rapid release core, which can be a monolithic (e.g., tablet) or multi-unit (e.g., pellet) type, and coating the core with a membrane. The membrane-modified core can then be further coated with a functional coating. In between the membrane-modified core and functional coating, a barrier or sealant can be applied. The mast cell stabilizer can be formed into an active core by applying the compound to a nonpareil seed. The at least one mast cell stabilizer can be applied with or without additional excipients onto the inert cores, and can be sprayed from solution or suspension using a fluidized bed coater (e.g., Wurster coating) or pan coating system. Alternatively, a mast cell stabilizer can be applied as a powder onto the inert cores using a binder to bind the mast cell stabilizer onto the cores. Active cores can also be formed by extrusion of the core with suitable plasticizers and any other processing aids as necessary.

The pharmaceutical solid oral dosage forms described herein can be further formulated to provide a controlled release of the mast cell stabilizer. Controlled release refers to the release of the mast cell stabilizer from a dosage form in which it is incorporated according to a desired profile over an extended period of time. Controlled release profiles include, for example, sustained release, prolonged release, pulsatile release, and delayed release profiles. In contrast to immediate release compositions, controlled release compositions allow delivery of an agent to a subject over an extended period of time according to a predetermined profile. Such release rates can provide therapeutically effective levels of agent for an extended period of time and thereby provide a longer period of pharmacologic response while minimizing side effects as compared to conventional rapid release dosage forms. Such longer periods of response provide for many benefits that are not achieved with the corresponding short acting, immediate release preparations.

In some embodiments, the solid dosage forms described herein can be formulated as enteric coated delayed release oral dosage forms, i.e., as an oral dosage form of a pharmaceutical composition as described herein which utilizes an enteric coating to affect release in the small intestine of the gastrointestinal tract. The enteric coated dosage form may be a compressed or molded or extruded tablet/mold (coated or uncoated) containing granules, powder, pellets, beads or particles of the active ingredient and/or other composition components, which are themselves coated or uncoated. The enteric coated oral dosage form may also be a capsule (coated or uncoated) containing pellets, beads or granules of the solid carrier or the composition, which are themselves coated or uncoated.

The term “delayed release” as used herein refers to the delivery so that the release can be accomplished at some generally predictable location in the intestinal tract more distal to that which would have been accomplished if there had been no delayed release alterations. In some embodiments the method for delay of release is coating. Any coatings should be applied to a sufficient thickness such that the entire coating does not dissolve in the gastrointestinal fluids at pH below about 5, but does dissolve at pH about 5 and above. It is expected that any anionic polymer exhibiting a pH-dependent solubility profile can be used as an enteric coating in the methods and compositions described herein to achieve delivery to the lower gastrointestinal tract. In some embodiments the polymers described herein are anionic carboxylic polymers. In other embodiments, the polymers and compatible mixtures thereof, and some of their properties, include, but are not limited to shellac acrylic polymers, cellulose derivatives, and poly vinyl acetate phthalate (PVAP).

Conventional coating techniques such as spray or pan coating are employed to apply coatings. The coating thickness must be sufficient to ensure that the oral dosage form remains intact until the desired site of topical delivery in the intestinal tract is reached.

Liquid Oral Formulations

Liquid formulation dosage forms for oral administration can be aqueous suspensions selected from the group including, but not limited to, pharmaceutically acceptable aqueous oral dispersions, emulsions, solutions, elixirs, gels, and syrups. See, e.g., Singh et al., Encyclopedia of Pharmaceutical Technology, 2nd Ed., pp. 754-757 (2002). In addition to the particles of a mast cell stabilizer, the liquid dosage forms may include additives, such as: (a) disintegrating agents; (b) dispersing agents; (c) wetting agents; (d) at least one preservative, (e) viscosity enhancing agents, (f) at least one sweetening agent, and (g) at least one flavoring agent. In some embodiments, the aqueous dispersions can further include a crystalline inhibitor.

Intranasal Formulations

Intranasal formulations are known in the art and are described in, for example, U.S. Pat. Nos. 4,476,116, 5,116,817 and 6,391,452, each of which is specifically incorporated by reference herein. The choice of suitable carriers is highly dependent upon the exact nature of the nasal dosage form desired, e.g., solutions, suspensions, ointments, or gels. Nasal dosage forms generally contain large amounts of water in addition to the active ingredient. Minor amounts of other ingredients such as pH adjusters, emulsifiers or dispersing agents, viscosity enhancing agents, preservatives, surfactants, gelling agents, or buffering and other stabilizing and solubilizing agents may also be present. In some embodiments, the nasal dosage form is isotonic with nasal secretions. In some embodiments a nasal dosage form is formulated to achieve sustained delivery. Examples of sustained delivery nasal dosage forms include, but are not limited to, dosage forms that include mucoadhesive agents such as microcrystalline cellulose. In some embodiments, systemically effective amounts of mast cell stabilizers are achieved with intranasal formulations by one or more of optimizing the droplet or particle size and including permeation enhancers in the intranasal formulation.

Buccal Formulations

Buccal formulations that include mast cell stabilizers may be administered using a variety of formulations known in the art. For example, such formulations include, but are not limited to, those described in U.S. Pat. Nos. 4,229,447, 4,596,795, 4,755,386, and 5,739,136, each of which is specifically incorporated by reference herein. In addition, the buccal dosage forms can further include a bioerodible (hydrolysable) polymeric carrier that also serves to adhere the dosage form to the buccal mucosa. The buccal dosage form is fabricated so as to erode gradually over a predetermined time period, wherein the delivery of the mast cell stabilizer is provided essentially throughout. Buccal drug delivery, as will be appreciated by those skilled in the art, avoids the disadvantages encountered with oral drug administration, e.g., slow absorption, degradation of the active agent by fluids present in the gastrointestinal tract and/or first-pass inactivation in the liver. With regard to the bioerodible (hydrolysable) polymeric carrier, it will be appreciated that virtually any such carrier can be used, so long as the desired drug release profile is not compromised, and the carrier is compatible with the mast cell stabilizer and any other components that may be present in the buccal dosage unit. Generally, the polymeric carrier comprises hydrophilic (water-soluble and water-swellable) polymers that adhere to the wet surface of the buccal mucosa. Examples of polymeric carriers useful herein include acrylic acid polymers, e.g., those known as “carbomers” (Carbopol®, which may be obtained from B.F. Goodrich, is one such polymer). Other components may also be incorporated into the buccal dosage forms described herein include, but are not limited to, disintegrants, diluents, binders, lubricants, flavoring, colorants, preservatives, and the like. In some embodiments, systemically effective amounts of mast cell stabilizers are achieved with buccal formulations by one or more of optimizing the erosion time of the formulation and by including permeation enhancers in the buccal formulations.

Transdermal Formulations

Transdermal formulations described herein may be administered using a variety of devices which have been described in the art. For example, such devices include, but are not limited to, those described in U.S. Pat. Nos. 3,598,122, 3,598,123, 3,710,795, 3,731,683, 3,742,951, 3,814,097, 3,921,636, 3,972,995, 3,993,072, 3,993,073, 3,996,934, 4,031,894, 4,060,084, 4,069,307, 4,077,407, 4,201,211, 4,230,105, 4,292,299, 4,292,303, 5,336,168, 5,665,378, 5,837,280, 5,869,090, 6,923,983, 6,929,801 and 6,946,144, each of which is specifically incorporated by reference in its entirety herein.

Transdermal dosage forms for use in the methods disclosed herein may incorporate certain pharmaceutically acceptable excipients which are conventional in the art. In one embodiment, the transdermal formulations include at least three components: (1) a formulation of a mast cell stabilizer; (2) a penetration enhancer; and (3) an aqueous adjuvant. In addition, transdermal formulations can include additional components such as, but not limited to, gelling agents, creams and ointment bases, and the like. In some embodiments, the transdermal formulation can further include a woven or non-woven backing material to enhance absorption and prevent the removal of the transdermal formulation from the skin. In other embodiments, the transdermal formulations described herein can maintain a saturated or supersaturated state to promote diffusion into the skin. In some embodiments, systemically effective amounts of mast cell stabilizers are achieved with transdermal dosage forms by including skin permeation enhancers in the transdermal dosage forms.

Transdermal formulations used in the methods described herein may employ transdermal delivery devices and transdermal delivery patches and can be lipophilic emulsions or buffered, aqueous solutions, dissolved and/or dispersed in a polymer or an adhesive. Such patches may be constructed for continuous, pulsatile, or on demand delivery of pharmaceutical agents. Still further, transdermal delivery of mast cell stabilizers can be accomplished by means of iontophoretic patches, microneedle systems, and the like. Additionally, transdermal patches can provide controlled delivery of the mast cell stabilizer. The rate of absorption can be slowed by using rate-controlling membranes or by trapping the compound within a polymer matrix or gel. Conversely, absorption enhancers can be used to increase absorption. An absorption enhancer or carrier can include absorbable pharmaceutically acceptable solvents to assist passage through the skin. For example, transdermal devices are in the form of a bandage comprising a backing member, a reservoir containing the compound optionally with carriers, optionally a rate controlling barrier to deliver the compound to the skin of the host at a controlled and predetermined rate over a prolonged period of time, and means to secure the device to the skin. In some embodiments, transdermal delivery of a mast cell stabilizer, e.g., cromolyn sodium, is provided using topical formulations of the mast cell stabilizer, e.g., cromolyn sodium.

Injectable Formulations

Formulations that include a mast cell stabilizer suitable for intramuscular, subcutaneous, or intravenous injection may contain physiologically acceptable sterile aqueous or non-aqueous solutions, dispersions, suspensions or emulsions, and sterile powders for reconstitution into sterile injectable solutions or dispersions. Examples of suitable aqueous and non-aqueous carriers, diluents, solvents, or vehicles including water, ethanol, polyols (propylene glycol, polyethylene-glycol, glycerol, cremophor and the like), suitable mixtures thereof, vegetable oils (such as olive oil) and injectable organic esters such as ethyl oleate. Proper fluidity can be maintained, for example, by the use of a coating such as lecithin, by the maintenance of the required particle size in the case of dispersions, and by the use of surfactants. Formulations suitable for subcutaneous injection may also contain additives such as preserving, wetting, emulsifying, and dispensing agents. Prevention of the growth of microorganisms can be ensured by various antibacterial and antifungal agents, such as parabens, chlorobutanol, phenol, sorbic acid, and the like. It may also be desirable to include isotonic agents, such as sugars, sodium chloride, and the like. Prolonged absorption of the injectable pharmaceutical form can be brought about by the use of agents delaying absorption, such as aluminum monostearate and gelatin.

For intravenous injections, compounds described herein may be formulated in aqueous solutions, preferably in physiologically compatible buffers such as Hank's solution, Ringer's solution, or physiological saline buffer. For transmucosal administration, penetrants appropriate to the barrier to be permeated are used in the formulation. Such penetrants are generally known in the art. For other parenteral injections, appropriate formulations may include aqueous or nonaqueous solutions, preferably with physiologically compatible buffers or excipients. Such excipients are generally known in the art.

Parenteral injections may involve bolus injection or continuous infusion. Pharmaceutical formulations for parenteral administration include aqueous solutions of the mast cell stabilizers in water-soluble form. Additionally, suspensions of the mast cell stabilizers may be prepared as appropriate oily injection suspensions. Suitable lipophilic solvents or vehicles include fatty oils such as sesame oil, or synthetic fatty acid esters, such as ethyl oleate or triglycerides, or liposomes. Aqueous injection suspensions may contain substances which increase the viscosity of the suspension, such as sodium carboxymethyl cellulose, sorbitol, or dextran. Optionally, the suspension may also contain suitable stabilizers or agents which increase the solubility of the compounds to allow for the preparation of highly concentrated solutions. Alternatively, the active ingredient may be in powder form for constitution with a suitable vehicle, e.g., sterile pyrogen-free water, before use. In some embodiments, parenteral formulations are prepared to provide sustained release of a mast cell stabilizer. In some embodiments, sustained release is provided by incorporating liposomes, stealth liposomes, bioerodible polymers, and the like into parenteral formulations to maximize the residence time in circulation and/or to increase absorption of the mast cell stabilizer.

Implantable Formulations

Formulations that include a mast cell stabilizer suitable for implantation may contain physiologically acceptable sterile aqueous or non-aqueous solutions, dispersions, suspensions, or emulsions. In some embodiments, the formulations are contained in and delivered from an osmotic pump implant to achieve sustained delivery of the mast cell stabilizer over long durations. In some embodiments, a mast cell stabilizer is formulated with a bioerodible polymer, which, upon administration facilitates the formation of a depot containing the mast cell stabilizer. The depot would then erode and release the mast cell stabilizer over a duration determined by the composition of the bioerodible polymer. In some embodiments, viscosity modifying agents, stabilizers, and other excipients may be used in the formulation to achieve optimum delivery over an extended duration.

Inhalation Therapy

An “inhalation device,” as used herein, refers to any device that is capable of administering a drug formulation to the respiratory airways of a patient. Inhalation devices include conventional inhalation devices such as metered dose inhalers (MDIs), dry powder inhalers (DPIs), jet nebulizers, ultrasonic wave nebulizers, heat vaporizers, and soft mist inhalers. Inhalation devices also include high efficiency nebulizers. Nebulizers, metered dose inhalers, and soft mist inhalers deliver pharmaceuticals by forming an aerosol which includes droplet sizes that can easily be inhaled. The aerosol can be used by a patient within the bounds of an inhalation therapy, whereby the mast cell stabilizer reaches the patient's respiratory tract upon inhalation. In some embodiments, the methods disclosed herein comprise administering to a patient a nominal dose of a mast cell stabilizer by an inhalation device. In some embodiments of the methods disclosed herein, an inhalation device is not a bronchoscope.

In some embodiments of the methods disclosed herein, administration of a composition comprising a mast cell stabilizer, e.g., cromolyn sodium, to a patient with an inhalation device, e.g., a high efficiency nebulizer, a dry powder inhaler, a metered dose inhaler, a thermal aerosol inhaler, or an electrohydrodynamic-based solution misting inhaler, is effective for the treatment or prophylaxis of a systemic mast cell related disorder because both a systemically effective amount of the mast cell stabilizer and a high deposited lung dose of the mast cell stabilizer is achieved in the patient. Thus, in some embodiments of the methods disclosed herein, administration of a composition comprising a mast cell stabilizer, e.g., cromolyn sodium, to a patient with an inhalation device, e.g., a high efficiency nebulizer, a dry powder inhaler, a metered dose inhaler, a thermal aerosol inhaler, or an electrohydrodynamic-based solution misting inhaler, is effective for the treatment or prophylaxis of a systemic mast cell related disorder that is not believed to be susceptible to treatment or prophylaxis with a mast cell stabilizer because both a systemically effective amount of the mast cell stabilizer and a high deposited lung dose of the mast cell stabilizer are achieved in the patient. Furthermore, in some embodiments where a mast cell stabilizer is administered with an inhalation device, e.g., a high efficiency nebulizer, a dry powder inhaler, a metered dose inhaler, a thermal aerosol inhaler, or an electrohydrodynamic-based solution misting inhaler, the methods disclosed herein provide improved efficacy for the treatment or prophylaxis of a systemic mast cell related disorder relative to administration of a systemically effective amount of the mast cell stabilizer by a different route of administration, e.g., parenterally or orally, because administration of the mast cell stabilizer with an inhalation device, e.g., a high efficiency nebulizer, a dry powder inhaler, a metered dose inhaler, a thermal aerosol inhaler, or an electrohydrodynamic-based solution misting inhaler, provides both a systemically effective amount of the mast cell stabilizer and a high deposited lung dose of the mast cell stabilizer in the patient. In some embodiments, a systemically effective amount of a mast cell stabilizer is achieved by delivering the mast cell stabilizer in an aerosol generated by a vibrating mesh nebulizer that produces droplets with a MMD of 3.0-4.0 μm and a GSD of 1.5-1.8. In some embodiments of the methods disclosed herein, an aerosol is administered through a mouthpiece of a nebulizer using normal tidal breathing.

Characterization of Inhalation Devices

The efficiency of a particular inhalation device can be characterized in many different ways, including by pharmacokinetic properties, lung deposition (deposited lung dose), respirable dose (RD), delivered dose (DD), respirable fraction (RF), respirable drug delivery rate (RDDR), volumetric or mass median diameter (VIVID or MMD), mass median aerodynamic diameter (MMAD) in combination with the geometric standard deviation (GSD), and total output rate (TOR), among others. The MMAD and GSD can be measured using a cascade impactor as described in United States Phamacopeia (USP<1601>). The DD can be measured by using breath simulation apparatus as described in USP<1601>. The RF is derived from measuring the amount of drug deposited on the cascade impactor plates with a particular cut-off particle size, and expressing that as a fraction of the total amount deposited on the cascade impactor plates, the induction port and the filter. The RD is calculated by multiplying the DD by the RF. The TOR is measured by the difference in weight of the nebulizer before and after completion of nebulization divided by the duration of nebulization. VIVID or MMD can be measured with a standard laser light scattering apparatus such as the Malvern Spraytec.

Pharmacokinetics is concerned with the uptake, distribution, metabolism and excretion of a drug substance. A pharmacokinetic profile comprises one or more biological measurements designed to measure the absorption, distribution, metabolism and excretion of a drug substance. One way of visualizing a pharmacokinetic profile is by means of a blood plasma concentration curve, which is a graph depicting mean active ingredient blood plasma concentration on the Y-axis and time (usually in hours) on the X-axis. Some pharmacokinetic parameters that may be visualized by means of a blood plasma concentration curve include AUC_(last), AUC_((0-∞)), C_(max), T_(1/2), and T_(max). An enhanced pharmacokinetic profile in a patient can be indicated by increased AUC_(last), AUC_((0-∞)), C_(max), or T_(1/2), a decreased T_(max), or an increased T_(max). Enhanced levels of a mast cell stabilizer in the blood plasma of a patient may result in better control of or improved symptoms of a systemic mast cell related disorder.

The deposited lung dose may be expressed as a percentage of the nominal dose that is deposited in the lung. For example, a lung deposition of 30% means 30% of the nominal dose is deposited in the lung. Likewise, a lung deposition of 60% means 60% of the nominal dose is deposited in the lung, and so forth. Lung deposition (deposited lung dose) can be determined using methods of scintigraphy or deconvolution.

RF, DD, RD, and RDDR are calculated parameters based on in vitro data that provide technical dimensions for the efficiency of an inhalation device. RF represents the percentage of the delivered aerosol, or inhaled mass, that penetrates into the gas-exchange region of the lungs. RF may be measured with a cascade impactor or laser diffraction apparatus. RF is expressed herein as the percentage of an aerosol delivered with an inhalation device that has a particular particle diameter or range of particle diameters. For example, the term “RF (≤3.3 μm)” as used herein refers to the percentage of an aerosol delivered with an inhalation device that has a particle diameter less than or equal to 3.3 μm. Similarly, the terms “RF (1-5 μm)” and “RF (≤5 μm)” as used herein refer to the percentage of an aerosol delivered with an inhalation device that has a particle diameter in the range of 1 μm to 5 μm, or less than 5 μm, respectively. DD is the portion or percentage of the nominal dose that is actually emitted from the mouthpiece of the device. The difference between the nominal dose and the DD is the amount of drug lost primarily as residues, i.e., the amount of drug remaining in the inhalation device after administration or lost in aerosol form. RD is an expression of the delivered mass of drug contained within droplets or particles having a certain diameter emitted from an inhalation device, such as a DPI, MDI, or nebulizer, that are small enough to penetrate into the lung of a patient. The RD is determined by multiplying the DD by the RF. RDDR is the speed at which a respirable dose of the drug is delivered to a patient's lungs. RDDR, measured as a function of f·g or mg/min, is determined by dividing the RD by the amount of time necessary for inhalation. The amount of time necessary for inhalation is measured as the amount of time from the first moment of administration of the emitted droplet or powder from the nebulizer, DPI, or MDI until the emitted or delivered droplet or powder of a respirable diameter is delivered to the lung.

Aerosol particle/droplet size is one factor determining the deposition of aerosol drugs in the airways. The distribution of aerosol particle/droplet size can be expressed in terms of one or more of VMD/MMAD and GSD. GSD is a dimensionless measure of a droplet size distribution curve relevant for characterizing terms such as VMD, MMD, and MMAD. In general, the smaller the GSD for a particular particle size distribution, the narrower the distribution curve.

Conventional Inhalation Devices

Conventional inhalation devices may be mechanical or electrical, and include, for example, jet nebulizers and ultrasonic nebulizers. Jet nebulizers generally utilize compressors to generate compressed air, which breaks the liquid medication into small breathable droplets, which form an aerosolized (atomized) mist. In some embodiments, when the patient breathes in, a valve at the top opens, which then allows air into the apparatus, thereby speeding up the mist generation; when the patient breathes out, the top valve closes, thereby slowing down the mist generation while simultaneously permitting the patient to breathe out through the opening of a mouthpiece flap. Some nebulizers may provide the aerosol in a continuous mode (e.g., the eFlow from PARI Pharma Starnberg), by a breath enhanced mode (e.g., the PART LC Plus or Sprint from PART Starnberg), by breath actuated mode dependent on the breathing pattern of the patient (e.g., the AeroEclipse from Trudell, Canada or the I-Neb from Philips Respironics), or according to given inhalation profile (e.g., the Akita from Activaero, Gmuenden, Germany).

Some conventional inhalation devices are disclosed in U.S. Pat. Nos. 6,513,727, 6,513,519, 6,176,237, 6,085,741, 6,000,394, 5,957,389, 5,740,966, 5,549,102, 5,461,695, 5,458,136, 5,312,046, 5,309,900, 5,280,784, and 4,496,086, each of which is hereby incorporated by reference in its entirety.

In some embodiments of the methods disclosed herein, compositions administered with dry powder inhalers comprise one or more of nanoparticles, spray dried materials, engineered porous particles with low mass median diameter but a high geometric diameter, liposomes, and stealth (or PEGylated) liposomes. In some embodiments, compositions administered by dry powder inhalers administered in the methods disclosed herein comprise nanoparticle clusters that aggregate into micrometer sized particles at neutral or basic pH but dissociate into nanoparticles at the pH encountered in the lung. In some embodiments the nanoparticle clusters comprise fumaryl diketopiperazine. In some embodiments, compositions administered with dry powder inhalers comprise lactose. In some embodiments, compositions administered with dry powder inhalers do not comprise lactose. In some embodiments, compositions administered with a dry powder inhaler have a MMAD between 2 and 4 μm, a GSD between 1.5 and 2.5 μm, and an RF 5 μm) between 30% and 80%. In some embodiments, a dry powder inhaler used to administer an inhalation formulation in the methods disclosed herein comprises a pre-metered dose, such as Plastiape Monodose inhaler, which comprises a capsule pre-filled with a powder. In some embodiments, a dry powder inhaler used to administer an inhalation formulation in the methods disclosed herein has a device-metered system such as Twisthaler, sold by Schering Plough, which comprises a reservoir to store a powder and a twisting top to dispense each dose. Inhalation formulations for administration with a dry powder inhaler may be prepared by blending a mast cell stabilizer, e.g., cromolyn sodium, with lactose, or spray drying a mast cell stabilizer, e.g., cromolyn sodium, or by pelletizing a mast cell stabilier, e.g., cromolyn sodium, to form free-flowing spherical agglomerates.

In some embodiments of the methods disclosed herein, compositions comprising mast cell stabilizers are administered with a metered dose inhaler. In some embodiments, a composition administered with a metered dose inhaler in the methods disclosed herein comprises one or more of nanoparticles, spray dried materials, engineered porous particles with low mass median diameter but a high geometric diameter, liposomes, and stealth (or PEGylated) liposomes.

In some embodiments of the methods disclosed herein, compositions comprising mast cell stabilizers are administered with a thermal aerosol inhaler. In some embodiments, the aerosol in a thermal aerosol inhaler is generated by directly heating and vaporizing a thin solid film of the mast cell stabilizer, e.g., cromolyn sodium, or by heating and vaporizing a solution of a mast cell stabilizer, e.g., cromolyn sodium in solvents such as propylene glycol and/or glycerol and water.

In some embodiments of the methods disclosed herein, compositions comprising mast cell stabilizers are administered with an electrohydrodynamic-based solution misting inhaler. In some embodiments, the aerosol in the electrohydrodynamic-based solution-misting inhaler is generated by subjecting a solution of a mast cell stabilizer, e.g., cromolyn sodium, or a liposome or pegylated liposome comprising a mast cell stabilizer, e.g., cromolyn sodium, to electrohydrodynamic forces through electrostatic energy.

High Efficiency Nebulizers

High efficiency nebulizers are inhalation devices that comprise a micro-perforated membrane through which a liquid solution is converted through electrical or mechanical means into aerosol droplets suitable for inhalation. High efficiency nebulizers can deliver a large fraction of a loaded dose to a patient. In some embodiments, the high efficiency nebulizer also utilizes one or more actively or passively vibrating microperforated membranes. In some embodiments, the high efficiency nebulizer contains one or more oscillating membranes. In some embodiments, the high efficiency nebulizer contains a vibrating mesh or plate with multiple apertures and optionally a vibration generator with an aerosol mixing chamber. In some such embodiments, the mixing chamber functions to collect (or stage) the aerosol from the aerosol generator. In some embodiments, an inhalation valve is also used to allow an inflow of ambient air into the mixing chamber during an inhalation phase and is closed to prevent escape of the aerosol from the mixing chamber during an exhalation phase. In some such embodiments, the exhalation valve is arranged at a mouthpiece which is removably mounted at the mixing chamber and through which the patient inhales the aerosol from the mixing chamber. Still yet, in some embodiments, the high efficiency nebulizer contains a pulsating membrane. In some embodiments, the high efficiency nebulizer is continuously operating.

In some embodiments, the high efficiency nebulizer contains a vibrating micro-perforated membrane of tapered nozzles that generates a plume of droplets without the need for compressed gas. In these embodiments, a solution in the micro-perforated membrane nebulizer is in contact with a membrane, the opposite side of which is open to the air. The membrane is perforated by a large number of nozzle orifices of an atomizing head. An aerosol is created when alternating acoustic pressure in the solution is built up in the vicinity of the membrane causing the fluid on the liquid side of the membrane to be emitted through the nozzles as uniformly sized droplets.

Some embodiments of high efficiency nebulizers use passive nozzle membranes and a separate piezoelectric transducer that stimulates the membrane. In contrast, some high efficiency nebulizers employ an active nozzle membrane, which use the acoustic pressure in the nebulizer to generate very fine droplets of solution via the high frequency vibration of the nozzle membrane.

Some high efficiency nebulizers contain a resonant system. In some such high efficiency nebulizers, the membrane is driven by a frequency for which the amplitude of the vibrational movement at the center of the membrane is particularly large, resulting in a focused acoustic pressure in the vicinity of the nozzle; the resonant frequency may be about 100 kHz. A flexible mounting is used to keep unwanted loss of vibrational energy to the mechanical surroundings of the atomizing head to a minimum. In some embodiments, the vibrating membrane of the high efficiency nebulizer may be made stainless steel, or of a nickel-palladium alloy by electroforming.

In some embodiments, a high efficiency nebulizer may be adapted or adaptable to operate in conjunction with a unit dosage form, such as an ampule or vial, which contains a single dose of a mast cell stabilizer composition for the treatment of a systemic mast cell related disorder. The unit dosage form comprises a container that contains an inhalation formulation comprising the mast cell stabilizer, such as cromolyn sodium. The container is adapted to cooperate with the high efficiency nebulizer device in such a way as to permit administration of the nominal dose of the inhalation formulation to a patient. In some embodiments, the high efficiency nebulizer and the unit dosage form are configured so that they are useable together, but not with other devices or dosage forms. In some particular embodiments, the unit dosage form is configured such that it fits into a keyhole-like structure in the high efficiency nebulizer, but will not operate with other nebulizer devices. In such embodiments, the high efficiency nebulizer is configured such that it will accept and properly operate with the unit dosage form containing the mast cell stabilizer, but not with other dosage forms.

Commercial high efficiency nebulizers are available from: PARI (Germany) under the trade name eFlow®; Aerogen, Ltd. (Ireland) under the trade names AeroNeb® Go and AeroNeb® Pro, AeroNeb® Solo, and other nebulizers utilizing the OnQ® nebulizer technology; Respironics (Murrysville, Calif.) under the trade names I-Neb®, Omron (Bannockburn, Ill.) under the trade name Micro-Air®; Activaero (Germany) under the trade name Akita®, and AerovectRx (Atlanta, Ga.) under the trade name AerovectRx®.

In some embodiments, the methods disclosed herein comprise administration to a patient a nominal dose of a mast cell stabilizer with a high efficiency nebulizer, wherein administration of the nominal dose of the mast cell stabilizer to the patient provides one or more of the following advantages: (1) an enhanced pharmacokinetic profile as compared to administration of an oral solution or an inhalation formulation with a conventional inhalation device; (2) an enhanced therapeutic effect as compared to administration of an oral solution or an inhalation formulation with a conventional inhalation device; (3) an enhanced lung deposition (deposited lung dose) as compared with a conventional inhalation device evidenced by scintigraphy or deconvolution, or derived from suitable in vitro indicators such as enhanced RD, RDDR, RF, and lower GSDs, as compared to administration with a conventional inhalation device; (4) reduced administration times, periods, and/or volumes as compared to administration with a conventional inhalation device; (5) a reduction in adverse side effects associated with oral formulations of a mast cell stabilizer, such as gastrointestinal irritation, or associated with conventional inhalation devices, such as cough; and (6) a longer duration of therapeutic effect as compared to administration of an oral solution or an inhaled formulation with a conventional inhalation device.

In some embodiments, the DD expressed as the percentage of the nominal dose of a mast cell stabilizer administered with a high efficiency nebulizer in the methods disclosed herein is at least about 30%, at least about 35%, at least about 40%, at least about 45%, at least about 50%, at least about 55%, at least about 60%, at least about 65%, about 65%, about 70%, about 30% to about 90%, about 40% to about 80%, about 45% to about 75%, about 50% to about 70%, about 30% to about 75%, about 40% to about 70%, about 45% to about 60%, or about 60% to about 70%.

TOR is the speed at which the liquid containing a mast cell stabilizer is administered from the inhalation device.

Example 3: Single-Dose, Dose Escalation Study Objectives: The Objectives of the Study are as Follows:

Primary:

Part 1: To determine the systemic availability and pharmacokinetic (PK) profile of single doses of a representative inhaled cromolyn sodium formulation (PA-101) delivered via a high efficiency nebulizer (eFlow®, PARI) using two different aerosol membranes (30 L and 40 L) in comparison with marketed formulations of cromolyn sodium (oral solution and an inhalation aerosol) in healthy subjects.

Secondary: To assess the safety and tolerability of PA-101 in comparison with marketed formulations of cromolyn sodium (oral solution and an inhalation aerosol).

Methodology:

This was a Phase 1, randomized, open-label, single-centre, dose-ranging, cross-over study conducted in two parts in total of 18 subjects. Part 1 was conducted in total of 12 healthy adult subjects of 18-45 years of age. Part 2 was conducted in a total of 5 adult patients of 18-45 years of age with systemic mastocytosis. Parts 1 and 2 were conducted in parallel.

Study Treatments, Dose and Mode of Administration: Part 1

-   -   1. 40 mg PA-101 (4% DSCG, 40 mg/l mL), oral inhalation via eFlow         30 L.     -   2. 80 mg PA-101 (4% DSCG, 80 mg/2 mL), oral inhalation via eFlow         30 L.     -   3. 40 mg PA-101 (4% DSCG, 40 mg/l mL), oral inhalation via eFlow         40 L.     -   4. 20 mg cromolyn sodium inhalation aerosol (1% DSCG, 20 mg/2         mL) (commercially available product), oral inhalation via LC         Plus.     -   5. 200 mg oral sodium cromoglycate solution (commercially         available product), oral administration.

Part 2:

-   -   1. 40 mg PA-101 (4% DSCG 40 mg/l mL), oral inhalation via eFlow         30 L     -   2. 200 mg oral sodium cromoglycate solution (commercially         available product), oral administration.

In Part 1, all study subjects received each study treatment in the morning (at 8:00 am, +/−30 minutes) as a single dose treatment. Prior to each dosing day, subjects were admitted to the clinic in the morning for baseline (pre-dose) assessments. Subjects were required to remain in the clinic for 12h after study drug administration on each dosing day. Treatment Visits were separated by a washout period of 2 to 5 days.

In Part 2, all study subjects received each study treatment three times daily (TID) (at 08:00 am, 14:00 μm and 20:00 μm, +/−30 minutes) as a single day treatment. Prior to each dosing day, subjects were admitted to the clinic in the morning for baseline (pre-dose) assessments. Subjects were required to remain in the clinic for 24h after study drug administration on each dosing day.

The main delivery device for administering PA-101 was the open system eFlow nebulizer using the 30 L aerosol head, which generates aerosol particles with a median size of about 3.0 μm. The 40 L aerosol head (generating aerosol particles with a median size of about 4.0 μm) was tested as a comparator arm in Part 1 only.

Duration of Study:

The duration of both Parts 1 and 2 of the study was one day.

Criteria for Evaluation:

Pharmacokinetic measurements: The PK parameters evaluated for plasma cromolyn sodium (DSCG) were maximum concentration (C_(max)), time to maximum concentration (T_(max)), terminal elimination half-life (T_(1/2)), area under the plasma concentration-time curve from time=0 to time of last measurable drug concentration (AUC_(0-t)), and area under the plasma concentration-time curve from time=0 to infinity (AUC_(0-∞)). Urine DSCG levels were measured for total DSCG excretion in the urine, and the bioavailability of the DSCG was calculated from the measured levels.

Safety measurements: Adverse events including gastrointestinal disturbance (e.g., abdominal pain, nausea, vomiting), changes in vital signs, 12-lead ECG and clinical laboratory tests (hematology, chemistry and urinalysis).

Statistical Measurements:

Pharmacokinetic parameters and plasma concentrations are listed and summarized. The summary statistics are presented as the geometric mean, arithmetic mean, arithmetic standard deviation (SD), min, median, max and n. The geometric statistics are not presented for Tmax.

Modeling of lung deposition with an aerosol from the 30 L and 40 L devices using the Finlay model (Finlay, W H, and A R Martin, “Recent advances in predictive understanding respiratory tract deposition”, Journal of Aerosol Medicine, Vol 21:189-205 (2008)) indicated that the lung deposition with the two devices should be very similar. However, the AUC value obtained with 40 mg dose using the 30 L device (338 ng*hr/mL) was surprisingly high compared to the value (212 ng*hr/mL) from the 40 L device. Cromolyn sodium is not metabolized in the body and is excreted intact via bile and urine. Cromolyn sodium deposited in the lung during inhalation will appear in the plasma, and the AUC would therefore be a surrogate for cromolyn sodium deposited in the lung. Any cromolyn sodium swallowed during inhalation will contribute negligibly to the AUC since the oral bioavailability of cromolyn is only about 1% (Richards et al, J Pharmacol Exp Ther, Vol. 241, No. 3: 1028-1032 (1987)). The AUC data therefore indicate that at the same dose (40 mg), the lung deposition with the 30 L device was surprisingly higher than that with the 40 L device.

The numbers of adverse events observed in the single dose study (Part 1) are shown in the following table:

Example 4: Efficacy Study Objective

The objectives of the study are: to determine the efficacy profile of cromolyn sodium inhalation formulation when administered using a high efficiency nebulizer in comparison with oral formulation of cromolyn sodium in patients with systemic mastocytosis; to assess the safety and tolerability of cromolyn sodium inhalation formulation when administered using a high efficiency nebulizer; to compare the pharmacokinetic profile of cromolyn sodium inhalation formulation when administered using a high efficiency nebulizer in comparison with oral formulation of cromolyn sodium in patients with indolent systemic mastocytosis.

Methodology

his is a Phase 2, randomized, double-blind, active-controlled, parallel arm, efficacy study in patients with indolent systemic mastocytosis.

At least about thirty six (36) adult human systemic mastocytosis patients are randomized to one of three treatment groups: (1) cromolyn sodium inhalation formulation administered thrice daily with a high efficiency nebulizer; (2) placebo formulation administered three times daily with a high efficiency nebulizer; and, (3) oral formulation of cromolyn sodium administered four times daily.

Following the Screening Visit (SV), eligible subjects enter a 4-week Washout/Baseline Period for daily assessment of baseline symptoms using a diary and to washout cromolyn sodium in oral cromolyn sodium users. At the end of the Washout Period, eligible subjects are randomized to receive cromolyn sodium inhalation formulation using a high efficiency nebulizer or oral cromolyn sodium formulation or placebo for 6 weeks.

The main criteria for inclusion are: a) Indolent systemic mastocytosis patients uncontrolled with antihistaminic therapy; b) 18-65 years of age; c) mastocytosis diagnosis confirmed by positive bone marrow biopsy; d) no recent systemic corticosteroid or immunosuppressive therapy; e) no history of cancer except basal cell carcinoma; and, f) no concurrent uncontrolled disease.

Criteria for Evaluation:

The primary efficacy variable is significant improvement in clinical symptoms at the end of treatment period following treatment with cromolyn sodium inhalation formulation when administered using a high efficiency nebulizer in comparison with oral formulation of cromolyn sodium.

The PK parameters evaluated for plasma cromolyn sodium are maximum concentration (Cmax), time to maximum concentration (T_(max)), terminal elimination half-life (T_(1/2)), area under the plasma concentration-time curve from time=0 to time of last measurable drug concentration (AUC_(0-t)), and area under the plasma concentration-time curve from time=0 to infinity (AUC_(0-∞)).

The safety parameters include adverse events (AEs) including assessment of gastrointestinal disturbance (e.g., abdominal pain, nausea, vomiting), and changes in vital signs and clinical laboratory tests.

Results:

At the end of the treatment period, patients exhibit a significant improvement in clinical symptoms with minimal AEs as compared to placebo and the oral formulation of cromolyn sodium.
